### On Thu, 20 Feb 2003 09:11:02 -0800, "Martin J. Levy" <[email protected]> ### casually decided to expound upon "David G. Andersen" <[email protected]>, ### William Allen Simpson <[email protected]> the following thoughts ### about "Re: scripts to map IP to AS?": MJV> Dave (and anyone that downloads lookup_as.c), MJV> MJV> Grab a newer version of traceroute.c -- There is a CLASSFULL piece of code MJV> within the 2.9.3 code-base used in lookup_as.c. The newer traceroute.c MJV> code removes the 192/8 & 128/8 testing. This is a cut-n-paste from the MJV> newer traceroute-nanog-6.3.0/traceroute.c. It can be cut-n-pasted into MJV> your code... Just a reminder to everyone who intends to query the IRR/RADB... Please be nice to the RADB whois server and don't DoS it. Open a persistant connection instead of one for each prefix lookup. For RADB and any other IRR server running IRRd, this can be accomplished by sending a "!!" in the beginning and keeping the connection open on your end in a seperate thread or something that you then issue the query to. For RIPE Whois based IRR servers, use the "-k" flag. -- /*===================[ Jake Khuon <[email protected]> ]======================+ | Packet Plumber, Network Engineers /| / [~ [~ |) | | --------------- | | for Effective Bandwidth Utilisation / |/ [_ [_ |) |_| N E T W O R K S | +=========================================================================*/
